The authors conclude that there is a statistically significant relationship between short-term exposure to higher air pollution and an increased risk of COVID-19 infection. The authors conclude that there is a statistically significant relationship between short-term exposure to higher air pollution and an increased risk of COVID-19 infection. The microbiological analysis revealed the presence of pathogens adsorbed to the particles [31] , and in alveolar cells and in the Summing up, the exposure to polluting agents alters the immune response of the lung cells and induces an increase in oxidative and inflammatory stress.	./cache/cord-353173-5c4n4tsf.txt	./txt/cord-353173-5c4n4tsf.txt
